摘要为了应对当前全球能源危机，近年来以太阳能发电的新兴产业发展迅猛而且有力。为了提高太阳能电池的发电效率，以多结太阳能电池为代表的光伏电池转化效率不断有了新的突破，并且多结太阳能电池广泛应用于卫星、宇宙飞船等。当前的研究热点是多结太阳能电池也叫做串联式太阳能电池，InGaN通过改变In组份可以实现禁带宽度从0.7EV到3.4EV的连续变化。单结及多结太阳能电池在太阳温度变化以及外界温度变化影响下，主要材料参数会发生一定的变化，而对应的最优能带选择必须针对不同的条件。针对这一情况，本文通过实验以及开发有效的仿真计算模型，对其内部的物理机制进行讨论和研究，通过计算发现在不同的黑体温度下，材料的最优能带值发生变化，意着在不同的应用条件下随着光谱特性的改变，太阳能电池所使用的材料特性将有所不同。63663

Title   Temperature Characteristics of Solar Cells

 Abstract The current global energy crisis worsening, therefore, in recent years, with emerging solar power industry is developing rapidly and powerful. Which, especially in single-junction solar cells and multi-junction solar cell conversion efficiency of photovoltaic cells represented continuously made new breakthroughs. Curr traditional energy sources such as oil, coal and other problems already facing depletion. Thereent solar cell there is a common drawback is the conversion efficiency is low, especially for satellites, spacecraft and other space applications. High conversion efficiency of solar cells is unquestionable benefits, because of the site area of exception is limited. Current research focus is also called multi-junction solar cells solar cells in series, InGaN In component by changing the band gap can be achieved from the continuous change 0.7EV to 3.4EV. Specifically, single-junction and multi-junction solar cells as well as the outside temperature changes in the sun under the influence of temperature changes, the main material parameters will be some changes, for this situation, the paper through experiments and the development of an effective simulation model, its the physical mechanism of internal discussion and research, and gives the change of the external heat carrier and the experimental data on the solar impact report. Also on the various parameters of the refractive index and extinction coefficient K N model is the focus of this sub-study.
